IUPUI researchers use computers to 'see' neurons to better understand brain function

INDIANAPOLIS— A study conducted by local high school students and faculty from the Department of Computer and Information Science in the School of Science at Indiana University-Purdue University Indianapolis reveals new information about the motor circuits of the brain that may one day help those developing therapies to treat conditions such as stroke, schizophrenia, spinal cord injury or Alzheimer's disease.

Transplanted human umbilical cord blood cells improved heart function in rat model of MI

Putnam Valley, NY. (Mar. 6, 2014) – When human umbilical cord blood cells were transplanted into rats that had undergone a simulated myocardial infarction (MI), researchers investigating the long term effects of the transplantation found that left ventricular (LV) heart function in the treated rats was improved over those that did not get the stem cells. The animals were maintained without immunosuppressive therapy.

Study suggests higher levels of omega-3 in diet are associated with better sleep

A randomised placebo-controlled study by the University of Oxford suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep. The researchers explored whether 16 weeks of daily 600 mg supplements of algal sources would improve the sleep of 362 children. The children who took part in the study were not selected for sleep problems, but were all struggling readers at a mainstream primary school.

Study: Classroom focus on social and emotional skills can lead to academic gains

WASHINGTON, D.C., March 6, 2014 ─ Classroom programs designed to improve elementary school students' social and emotional skills can also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building, according to a study to be published this month in American Educational Research Journal (AERJ). The benefit holds true for students across a range of socio-economic backgrounds.

Black boys viewed as older, less innocent than whites, research finds

WASHINGTON – Black boys as young as 10 may not be viewed in the same light of childhood innocence as their white peers, but are instead more likely to be mistaken as older, be perceived as guilty and face police violence if accused of a crime, according to new research published by the American Psychological Association.

Half the survivors in 1 Japanese town have PTSD symptoms

Though just two of Hirono's 5,418 residents lost their lives in Japan's mega-earthquake and tsunami, a new study shows that the survivors are struggling to keep their sanity.

One year after the quake, Brigham Young University professor Niwako Yamawaki and scholars from Saga University evaluated the mental health of 241 Hirono citizens. More than half of the people evaluated experienced "clinically concerning" symptoms of post-traumatic stress disorder. Two-thirds of the sample reported symptoms of depression.

LSUHSC mental health care model reduced symptoms in those most affected by BP oil spill

New Orleans, LA – A model of care developed by the Department of Psychiatry at LSU Health Sciences Center New Orleans School of Medicine to provide mental health services after the Deepwater Horizon Gulf Oil Spill reduced both mental health and general medical symptoms. The novel approach embedded psychiatrists, psychologists, social workers and telemedicine resources into primary care clinics in the most affected areas. This new model can be used in communities at risk for disasters and rural communities with limited mental health resources.

Atypical development in the siblings of children with autism is detectable at 12 months

(SACRAMENTO, Calif.) — Atypical development can be detected as early as 12 months of age among the siblings of children with autism spectrum disorder, a study published by researchers with the UC Davis MIND Institute and UCLA has found.

Restless legs syndrome may signify bigger health problems

(Boston)--A nationally-recognized sleep expert has published an editorial describing Restless Legs Syndrome (RLS) as a possible biomarker for underlying disease. The editorial appears in the March 5, 2014 issue of Neurology the medical journal of the American Academy of Neurology and was authored by Boston Medical Center neurologist Sanford H. Auerbach, MD.

RLS is a disorder of the nervous system. Patients with RLS have uncomfortable sensations in their legs which lead to an overwhelming urge to move them – most often at night or whenever the patient is resting.

UF researchers find drug therapy that could eventually reverse memory decline in seniors

GAINESVILLE, Fla. — It may seem normal: As we age, we misplace car keys, or can't remember a name we just learned or a meal we just ordered. But University of Florida researchers say memory trouble doesn't have to be inevitable, and they've found a drug therapy that could potentially reverse this type of memory decline.

UCSB study explores cocaine and the pleasure principle

(Santa Barbara, Calif.) — On the other side of the cocaine high is the cocaine crash, and understanding how one follows the other can provide insight into the physiological effects of drug abuse. For decades, brain research has focused on the pleasurable effects of cocaine largely by studying the dopamine pathway. But this approach has left many questions unanswered.

Blocking immune system protein in mice prevents fetal brain injury, but not preterm birth

An inflammatory protein that triggers a pregnant mouse's immune response to an infection or other disease appears to cause brain injury in her fetus, but not the premature birth that was long believed to be linked with such neurologic damage in both rodents and humans, new Johns Hopkins-led research suggests.
